摘要
A photochromic curable composition that contains a (meth)acrylate compound represented by the following formula (1-X1); (wherein Y is an oxygen atom or a divalent group represented by -NH-, R 1 and R 2 are hydrogen atoms or methyl groups, R 3 is an alkylene group having 1 to 6 carbon atoms, R 4 is an alkylene group having 1 to 6 carbon atoms, a cycloalkylene group having 3 to 8 carbon atoms and which may include a double bond, or an arylene group having 6 to 10 carbon atoms, and a is a positive number of 1 to 20), other radically polymerizable monomers and a photochromic compound. The invention provides a lens that features excellent durability and high photochromic property free of the problems of turbidity in the surfaces of the lens caused by bleed out or the peeling in the step of production.
